CQNFORMING-GAGE.

Specification of Letters Patent.

Patented Nov. 14, 1911.

Application filed. March 16, 1911. Serial No. 614,808.

To all whom it may concern:

Be it known that I, DAVID S. HUMPHREY, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented a certain new and useful Improved Conforming-Gage, of which thefollowing is a specification.

This invention relates to improvements in conforming gages, andprimarily to that class of gages employed in cutting mortises for doorhinges and the like.

The principal object of the invention is to provide means for quicklyand accurately determining the width, depth and length of the mortiserequired.

The invention also relates to certain details of construction. whichwill. be hereinafter described and perhaps claimed. reference being hadto theaccompanying drawings in which a preferred adaptation of theinvention is shown.

Figure 1 is a face view of the improved gage, also showing a fragment ofa door to which it is attached, and a chisel in position in dotted linesfor cutting the mortise. Fig. 2 is an end view of the improved gage.Fig. 3 is an enlarged transverse section through the improved gage online 3 3 Fig. 1. Fig. 4 is an enlarged fragmentary horizontal sectionthrough the improved gage on line 4-4 Fig. 1. Fig. 5 is an enlargedfragmentary transverse section through the improved gage on line 5-5Fig. 1. Figs. 6, 7 and 8 are enlarged detached details of the taperingwedge members for regulating the depth of the mortise.

In referring to the adaptation of the invention shown in theaccompanying drawings in detail, like numerals designate like parts.

This improved gage consists of a plurality of members adjustablyconnected to each other and capable of independent adjustment toregulate the width, depth and length of the mortise to be cut..

The. adaptation of the gage illustrated consists of a rear longitudinalmember 1, a forward longitudinal member '2, and two transverseconnecting members 3 and 4. The

rear longitudinal member 1 is preferably the longest member of the gage,and is provided with a longitudinal slot 5.

Two loop members 6 are fastened to the front face or side surface of therear longitudinal member 1, near the ends thereof, by screws 7 or thelike, and are each provided with a comparatively large upper opening 8,and a comparatively small lower opening 9, which registers with theupper opening. The loop members are of a substantially square outline,and a tubular element or socket 10 is slidably mounted in the largeopening 8 in each loop member, and is restrained against removaltherefrom by upper and lower enlargements 11 and 12, located at therespective upper and lower ends of the socket.

An ordinary wire nail, or other suit-able element, 13, is fitted looselyin each socket and is adapted to be driven into the door, or doorcasing, to temporarily fasten the gage to the door or casing.

The transverse connecting members, 3 and 4, are provided with verticalflanges, 14, at their rear ends through which screws, 15, are fitted tosecure said transverse connecting members to the rear longitudinalmember 1. One of the screws, 15, in the adaptation illustrated in theaccompanying drawings, screws into a slide block, 16, slidably mountedin the slot, 5, to provide for the adjustment of the transverse memberstoward or from each other for the purpose of determining the length ofthe mortise. The complementary walls of the slot, 5, and edges of theblock, 16, are correspondingly tapered, as shown at 17, in Fig. 3, tolock the block in the slot against transverse forward movement.

The forward longitudinal member, 2, is disposed with its faces or sidesurfaces at substantially right angle to the faces or side surfaces ofthe rear longitudinal member, and is arranged to extend beneath and tobe attached to the transverse members 3 and 4, in front of the rearlongitudinal member 1. The forward longitudinal member is so supportedthat it is capable of adjustment backward or forward, or in other words,toward or from the rear longitudinal member to regulate the width of themortise to be cut, and also of independent adjustment up or downrelatively to the transverse members to regulate the depth of themortise. the transverse members is provided with depending side flanges,18, and an end flange, i

19, and the space between said side flanges, l8,- constitutes aslideway, 20, in which a wedge device is adjustably and slidablyarranged. Each of the transverse members is also provided with alongitudinal slot, 21.

The preferable form of wedge device employed consists of an uppertapering wedge member, 22, and a lower tapering wedge member, 28, saidwedge members being slidably arranged in the slideway, 20, of one of thetransverse members and having diagonally extending contacting faces. Theupper wedge member, 22, is provided with a depending enlargement, 24,which projects into a longitudinal groove, 25, in the top surface of thelower wedge member, 23, and serves to prevent lateral movement of onewedge member relatively to the other. Each of the wedge devices isadapted to be locked in its adjusted position in the slideway of thetransverse member inwhich it is arranged by a bolt or screw, 26,- whichpasses-through the longitudinal slot, 21, in the transverse member, alongitudinal slot, 27 in the upper wedge member and an opening, 28, inthe lower wedge member. The bolt or screw, 26, also passes through theforward longitudinal member and thus additionally serves to fasten theforward longitudinal member to the transverse members. The forwardlongitudinal member is provided with a longitudinal slot, 29, throughwhich one ofthe bolts, 26, passes, thereby providing for longitudinaladjust. ment of the bolt in the forward longitudinal member to permitthe adjustment of the transverse members relatively to each other. Inthe adaptation shown, the bolt or screw, 26, is passed up through theslot or opening in the forward longitudinal member, then through theopening in the lower wedge member, the slot in the upper wedge memberand the slot in the transverse connecting member, and a butterfly nut,30, is screwed upon the upper projecting end of the bolt or screw, 26,to fasten all of the parts in their adjusted position. If desired, thehead of the bolt, or screw, 26, may be made comparatively thin, andslight depending horizontal flanges, 31, may be provided on the undersurface of the forward longitudinal member in parallel separated.arrangement, as shown. in Figs. 2 and 3, between which the head .of thebolt or screw is located as shown. The purpose of these flanges is toprovide means for preventing contact between the head of the Each of isprovided with a vertical projection, 32,

which extends through the slot in the transverse connecting member, asshown in Fig. 2, and forms a convenient means for adjusting the wedgemember.

In cutting a mortise with the aid of this improved gage, the hinge isfirst placed in the gage and the members of the gage are adjustedrelatively to the said hinge to obtain the proper width, depth andlength for the mortise, and are then fastened in their adjustedpositions: the hinge is then removed and the gage is temporarilyattached to the desired portion of the door or casing, by placing it inposition and driving the nails, 13, into the surface of the wood. Themortise can then be quickly and accurately cut by a carpenter with achisel or other suitable cutting tool; the members of the gage exactlydefining the width, depth and length of the cut to be made, and guidingthe tool, to guard against any cut or mar of the wood exterior, to theproper outlines of the mortise.

The great advantage of this improved gage is that it enables a carpenterto very quickly and accurately cut a mortise of any desired size.

While this improved gage is chiefly adapted for setting door hinges, itshould be understood that it is also equally adapted for and may beutilized for many other purposes in which it is necessary to secure anaccurate mortise.
